Title: Controller for vehicle engine
Inventor: ISHII KIYOSHI
IPC: F02D37/00
Filed: 1979-09-19
Abstract: PURPOSE: To restrain excessive reduction of mixture's charging efficiency by keeping a throttle valve open only a little and to reduce an engine power by delaying an ignition timing, in deceleration, thereby compensating an engine-brake reduced due to the aforesaid opening of the throttle valve.  
     CONSTITUTION: When a vehicle is decelerated from high speed running by releasing an acceleration pedal, an abrupt closing of a throttle valve 2 causes a rise in suction negative pressure. A negative pressure is carried from a negative pressure detecting opening D 2  into a negative pressure chamber 9 of a negative pressure actuated valve 5 to pull down a diaphragm 8 so that a valve body 12 is opened. A one-way valve 6 is also opened so the suction negative pressure is transferred into a negative pressure chamber of a negative pressure motor 3, which makes the throttle valve 2 kept open to a certain little degree. The negative pressure from the negative pressure detecting opening D 2 , which is to run through a line L 3  via a relief valve 19 to a negagive pressure motor 7 related to an ignition distributor 15, is weakened because a negative pressure leak duct 21 of the relief valve 19 is opened through by pulling down a valve body 23. Thereby an ignition timing control rod 16 is shifted to a delay.

Title: Heat treating device for wafer
Inventor: KITAHARA TOSHIAKI
IPC: C30B31/14
Filed: 1980-09-03
Abstract: PURPOSE:To prevent the occurrence of a crystalline defect in a wafer by employing a material having large thermal capacity and standing jigs for maintaining the predetermined interval between the material and the wafers, and heat treating the wafer. CONSTITUTION:A thick jig 2 is formed of a material having relatively large thermal capacity, e.g., quartz, SiC or the like, and standing jigs 7 are engaged at the lower edges with the slits 6 on the upper surface of the jig 2. The jigs 7 are formed also of quartz, SiC or the like, and are square thick plates slightly larger than the wafer 1. A spherical recess 8 of the diameter approximately equal to the diameter of the wafer is formed on one side surface of the jig 7, hooks 9 are provided at upper and lower, right and left sides of the periphery of the recess, and the wafer 1 is thus engaged. Thus, the gap e between the surface of the wafer 1 and the jig 7 becomes gradually large toward the center from the periphery. In this manner, the periphery and the center of the wafer are heat at approximately equal temperature, and when the wafer is removed of a reaction tube, the periphery of the wafer is suppressed in cooling by the residual heat, thereby equalizing the temperature difference between the periphery and the center of the wafer. Thus, the thermal stress is not concentrated to the periphery, and no crystalline defect is produced.

Title: Semiconductor dynamic ram
Inventor: MIYATAKE HIDEJI
IPC: G11C11/409
Filed: 1990-05-10
Abstract: PURPOSE:To attain high speed processing by providing an N-channel transfer gate onto bit lines between a memory cell array and sense circuit and a re- charge circuit, bringing its gate level to a low level before sense recharge activation and to a high level after the end of activation. CONSTITUTION:When a word line WL rises, information of a memory cell is delivered to bit lines B2, B1, an RXD signal gets a high level, an S1 signal goes to a low level to disconnect bit line pairs B1/B1 and B2/B2. Then a sense active signal So goes to a high level and a recharge activation signal goes to a low level, then the sense, recharge of the line B1/B1 are finished. Furthermore, since an output (y) of a column decoder goes to a high level to deliver the information of the bit line B1/B1 to an I/O line, the level difference of the bit lines B1/B1 is fast and the timing when the column decoder output (y) rises is quickened, the RXD signal after the end of sense, recharge goes to a low level and an S1 signal goes to a high level. Thus, the access time of a RAM is quickened.
